As other reviewers have said these are pretty stiff but on a gym wall that is nice for some good edging. The first time I wore them I was pretty disappointed because the edges were just peeling off on every route and they weren't sticky. I have been in them 2-3 times a week now for a month and they are much more sticky and the edges have stopped peeling. They are a huge upgrade from rental shoes, and for a decent price. I have also used them sport climbing and they have worked out pretty well. I usually wear a 10.5 and I ordered a 43 which was a little uncomfortable initially but they are stretching out and virtually no pain is occurring, making me wish I would have ordered another have a size down for better feel. They are very comfortable also and fit my foot well. They get me up sport 5.11's.
